Manufacturer's warranty – tools
Hilti warrants that the tool supplied is free of defects
in material and workmanship. This warranty is valid so
long as the tool is operated and handled correctly,
cleaned and serviced properly and in accordance with
the Hilti Operating Instructions, and the technical sys-
tem is maintained. This means that only original Hilti
consumables, components and spare parts may be
used in the tool.
This warranty provides the free-of-charge repair or
replacement of defective parts only over the entire lifes-
pan of the tool. Parts requiring repair or replacement
as a result of normal wear and tear are not covered by
this warranty.
Additional claims are excluded, unless stringent
national rules prohibit such exclusion. In particular,
Hilti is not obligated for direct, indirect, incidental
or consequential damages, losses or expenses in
connection with, or by reason of, the use of, or inabil-
ity to use the tool for any purpose. Implied warranties
of merchantability or fitness for a particular purpose
are specifically excluded.
For repair or replacement, send tool or related parts
immediately upon discovery of the defect to the address
of the local Hilti marketing organization provided.
This constitutes Hilti's entire obligation with regard to
warranty and supersedes all prior or contemporane-
ous comments and oral or written agreements con-
cerning warranties.
For repair or replacement, contact your local Hilti rep-
resentative at:
(US) 1-800-879-8000
(Canada) 1-800-363-4458
Disposal
Handling drilling and sawing slurry
Working with diamond tools on mineral materials (e.g.
concrete) in a wet process produces drilling or sawing
slurry. As with fresh cement mortar, it may cause irrita-
tion if allowed to come into contact with the skin or eyes.
Wear protective clothing, protective gloves and goggles.
With regard to environmental aspects, allowing these
slurries to flow directly into rivers, lakes or the sewer-
age system without suitable pre-treatment is problem-
atical.
Disposal procedure
In addition to the following recommended pre-treatment
procedures, the applicable national regulations must be
observed when disposing of drilling or sawing slurry.
Ask the local authorities concerned for further informa-
tion.
Recommended pre-treatment
■
Collect the drilling or sawing slurry (e.g. using a suit-
able industrial vacuum cleaner).
■
The fine content of the drilling or sawing slurry should
be separated from the water by allowing it to settle
(e.g. leave standing for some time or add a coagu-
lation agent).
■
Solid material from the drilling or sawing slurry should
be deposited at a construction waste disposal site.
■
Water from the drilling or sawing slurry should be
neutralised (e.g. by adding a large quantity of water
or other neutralisation agents) before it is allowed to
flow into the sewerage system.
